Wideband slow-light modes for time delay of ultrashort pulses in symmetrical metal-cladding optical waveguide

Opt Express. 2012 Apr 23;20(9):9409-14. doi: 10.1364/OE.20.009409.

Abstract

A widebandwidth optical delay line is a useful device for various fascinating applications, such as optical buffering and processing of ultrafast signal. Here, we experimentally demonstrated effective slow light of sub-picosecond signal over 10 THz frequency range by employing the wide slow light modes in thick symmetrical metal-cladding optical waveguide (SMCOW). Ultrahigh-order guided modes travelling as slow light in waveguide together with strong confinement provided by metal-cladding makes this scheme nearly material dispersion independent and compatible with wide bandwidth operation.
